Electron beam sintering of ceramics for additive manufacturing

Vacuum, 2019
Abstract We describe the results of electron-beam layer-by-layer sintering of a mixture of alumina powder and talc. An electron beam with high power density, generated by a forevacuum-pressure, plasma-cathode electron source, was used as heat source. A specific feature of the source is the option to generate an electron beam at pressure range 5–20 Pa.

Temperature Measurements in Powder-Bed Electron Beam Additive Manufacturing

Volume 2A: Advanced Manufacturing, 2014
Thermal characteristics such as process temperatures and melt pool sizes offer important information in metal additive manufacturing (AM) technologies such as powder-bed electron beam additive manufacturing (EBAM). In this study, a near infrared (NIR) thermal imager was employed to acquire build surface process temperatures during EBAM fabrications ...

Overhang Support Structure Design for Electron Beam Additive Manufacturing

Volume 2: Additive Manufacturing; Materials, 2017
Overhang structures are commonly found in Powder-bed metal additive manufacturing (AM) such as electron beam additive manufacturing (EBAM) process. The EBAM is assumed to build overhang structure without support features since powder bed could provide support.

Dynamic tensile behavior of electron beam additive manufactured Ti6Al4V

Materials Science and Engineering: A, 2015
Abstract High rate and quasi-static tensile experiments examined strain rate dependence on flow stress and strain hardening of additive manufactured Ti6Al4V. Variations on strain-hardening coefficient indicate that the rate of thermal softening is greater than strain hardening during plastic deformation.

Phase-field simulation of microstructure evolution in electron beam additive manufacturing

The European Physical Journal E, 2020
Electron beam additive manufacturing (EBAM) is an emerging additive manufacturing technology with extremely high energy beam. The rapid solidification in the molten pool is of interest but not fully understood. In EBAM, with both large thermal gradient and cooling rate, the microstructure evolution during solidification is difficult to be described ...

Wire feed electron beam additive manufacturing of metallic components

AIP Conference Proceedings, 2018
The results of the research show that it is possible to make axisymmetric blanks of satisfying quality and geometrical sizes using the process of wire feed electron additive manufacturing (3D-printing). Yield strength of blank’s material achieves 317 MPa, which is higher than that of base cast metal (SS321). It was figured out that varying the additive

Investigation of corrosion properties of electron beam additive manufactured AA5356

AIP Conference Proceedings, 2020
In this paper, the corrosion resistance of 5356 alloy samples produced using additive electron beam technology was explored. The printed samples were of different composition of the main alloying element—magnesium. It is observed that with an increase in the magnesium content in the samples, the polarization behavior of the samples worsens, reducing ...

Peculiarities of Control over Electron-Beam Additive Form Manufacturing

Surface Engineering and Applied Electrochemistry, 2019
This work analyzes the manufacturing process of an electron-beam additive form by heating as a result of remelting the supplied filler wire as a control object. Control actions and output values are designated that can be used in constructing a control systems with feedback.

Thin-Wire Multi-Material Electron Beam Additive Manufacturing

Metal Additive Manufacturing (MAM) has experienced significant growth in industrial applications in recent years. Laser-based AM methods are more widely adopted in industry due to their simpler operation and lower maintenance requirements; however, they face limitations when processing reflective metals such as copper, as well as materials with high ...
